850MHz, Output Limiting, Low Distortion
Current Feedback Operational Amplifier
Features
• User Programmable Output Voltage Limits
The HFA1130 is a high speed wideband current feedback
amplifier featuring programmable output limits. Built with
Intersil’s proprietary complementary bipolar UHF-1 process,
it is the fastest monolithic amplifier available from any
semiconductor manufacturer.
• Low Distortion (30MHz, HD2) . . . . . . . . . . . . . . . . -56dBc
• -3dB Bandwidth . . . . . . . . . . . . . . . . . . . . . . . . . . 850MHz
• Very Fast Slew Rate. . . . . . . . . . . . . . . . . . . . . . 2300V/µs
• Fast Settling Time (0.1%). . . . . . . . . . . . . . . . . . . . . . 11ns
This amplifier is the ideal choice for high frequency
applications requiring output limiting, especially those needing
ultra fast overdrive recovery times. The output limiting function
allows the designer to set the maximum positive and negative
output levels, thereby protecting later stages from damage or
input saturation. The sub-nanosecond overdrive recovery time
quickly returns the amplifier to linear operation, following an
overdrive condition.
• Excellent Gain Flatness
- (100MHz) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.14dB

- (30MHz) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.01dB
• High Output Current. . . . . . . . . . . . . . . . . . . . . . . . . 60mA
• Overdrive Recovery . . . . . . . . . . . . . . . . . . . . . . . . . <1ns
• Pb-Free Plus Anneal Available (RoHS Compliant)
The HFA1130 offers significant performance improvements
over the CLC500/501/502.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
